Subway renovations at the Seventh Avenue subway station have left Park Slope straphangers railroaded into walking outside between exits.

That's because the F and G mezzanine between Seventh and Eighth avenues is permanently closed. 

MTA officials say sealing the passage will actually make access faster and easier -- but some travelers say it's crazy to make them walk outside in the rain.

The $400,000 renovation also includes adding new turnstiles and moving the station agent booth from the center to the Seventh Avenue side.
